🗓 Next intake: September 2026
The Ontario Secondary School Diploma is Canada's most widely recognized high school credential — accepted by top universities in over 30 countries.
Issued by an Ontario Ministry of Education–accredited partner school. Your diploma carries the same weight as any Canadian student's — wherever you go.
Students complete 18 compulsory credits and 12 elective credits across subjects like English, Mathematics, Science, and the Arts — fully taught in English.
Unlike A-Levels or IB, OSSD is assessed through coursework, projects, and teacher evaluation — reducing exam stress while maintaining rigorous standards.
We don't just deliver the curriculum — we create the conditions for every student to thrive.
All OSSD courses are delivered by Ontario-certified educators with experience teaching the curriculum in Canada and internationally.
Our Vietnamese-speaking academic advisors guide families through course selection, university applications, and student wellbeing.
Dedicated university counseling from Grade 10 — helping students build competitive profiles for top-ranked institutions worldwide.
Maximum 18 students per class ensures your child receives individual attention and builds real relationships with their teachers.
Our program welcomes students at different stages — whether starting fresh or transferring from another curriculum.
The ideal entry point. Students build credits from the ground up, giving them maximum flexibility to shape their course choices and university pathway.
